论文摘要
在毫米波（MMWave）频段上具有多输入 - 元素输出（MIMO）体系结构的完全数字宽带式连接雷达（JCR），将使高关节通信和雷达性能具有增强的设计灵活性。具有少量类似物对数字转换器（ADC）的量化接收器将实现实用的JCR解决方案，用于减少未来派便携式设备和自动驾驶汽车的功耗。在本文中，我们提出了一个名为JCR70的联合通信射线概念验证平台，以使用71-76 GHz频段中的真实通道测量值评估和演示这些JCR系统的性能。我们通过扩展使用额外的全双工雷达接收器的MMWave通信设置来开发此平台，并使用滑动导轨上的移动天线捕获MIMO JCR通道。为了表征我们开发的测试的JCR性能，我们进行了多个室内和室外实验，并在测量数据上应用传统和高级处理算法。此外，我们将JCR70平台的性能与Inras Radarbook的性能进行了比较，Inras Radarbook是一个最先进的汽车雷达评估平台，位于77 GHz。结果表明，具有2-4位ADC的量化接收器通常非常接近高分辨率ADC，最高可达5 dB的信噪比。我们的JCR70平台在73 GHz和2 GHz带宽处具有完全数字JCR波形，由于更高的带宽和较大的合成天线孔径，因此具有更高的分辨率能力。
A fully-digital wideband joint communication-radar (JCR) with a multiple-input-multiple-output (MIMO) architecture at the millimeter-wave (mmWave) band will enable high joint communication and radar performance with enhanced design flexibility. A quantized receiver with few-bit analog-to-digital converters (ADCs) will enable a practical JCR solution with reduced power consumption for futuristic portable devices and autonomous vehicles. In this paper, we present a joint communication-radar proof-of-concept platform, named JCR70, to evaluate and demonstrate the performance of these JCR systems using real channel measurements in the 71-76 GHz band. We develop this platform by extending a mmWave communication set-up with an additional full-duplex radar receiver and by capturing the MIMO JCR channel using a moving antenna on a sliding rail. To characterize the JCR performance of our developed tested, we conduct several indoor and outdoor experiments and apply traditional as well as advanced processing algorithms on the measured data. Additionally, we compare the performance of our JCR70 platform with the INRAS Radarbook, which is a state-of-the-art automotive radar evaluation platform at 77 GHz. The results demonstrate that a quantized receiver with 2-4 bit ADCs generally performed quite close to the high-resolution ADC for a signal-to-noise ratio of up to 5 dB. Our JCR70 platform with a fully digital JCR waveform at 73 GHz and 2 GHz bandwidth achieved higher resolution capability than the Radarbook due to higher bandwidth and larger synthesized antenna aperture.
